REMOVABLE MACHlNE-TREADLE.

Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed December 4, 1905. Serial No. 290.100.

To all whom it may concern:

Be it known that I, STANISLAS DENIS BAOHAND, a subject of the King of Great Britain, residing at Coaticooke, county of Stanstead, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Removable Machine-Treadles and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to sewing-machines.

The object of my invention is to provide means for attaching the treadle to an ordinary form of library-table, so that the treadle may be wholly removed.

A further object is to provide a treadle which may be removed and folded into a small space; and my invention consists of the construction, combination, and arrangement of parts, as herein illustrated, described, and claimed.

In the accompanying drawings, forming part of this application, I have illustrated one form of embodiment of my invention, in which drawings similar reference characters designate corresponding parts, and in which Figure 1 is a perspective view of an ordinary form of table used to support the head of a sewing-machine. Fig. 2 is a side elevation of a removable treadle. Fig. 3 is a front elevation of the removable treadle. Fig. 1 is a bottom plan view of a portion of the shelf of the table shown in Fig. 1. Fig. 5 is a detached plan view of a spring used in my invention, and Fig. 6 is a vertical section on line 6 6 of Fig. 4.

Referring to the drawings, 1 designates a table of ordinary construction and similar in contour to the one now in public use for the purposes of supporting a sewing-machine head, and which table is provided with a leaf 2, supported by its legs.

Disposed on the under surface adjacent one end of the leaf 2 are sleeves 3, Fig. 4, which sleeves are provided with lugs 4, adapted to furnish means whereby the sleeves may be secured to the table, and secured on one of the lugs 4 is a spring 5.

The treadle-frame comprises the standards 6, adapted to support an axle 7 adjacent their upper ends, Carried by one end of the axle 7 is a crank 8, and carried by the opposite end is a driving-wheel 9. Secured to the crank S is a connecting-rod 10. Connected to one of the standards 6 is a horizontal member 11, having a bent outer end '12 and having its oppositeend pivoted, as at 13,, to one of the standards 6. Rockably disposed on the horizontal member 11 is a treadle 14, providedwith an extension 15, which is pivotally connected at 16 to the lower end of the connecting-rod 10. pivoted end of the member 11 is a spring 17, provided with a bent free end 17 which is adapted to engage the lower end of the standards 6, to which the member 11 is pivoted, and to hold said member against movement when it is in a horizontal position with relation to the standards 6. Intermediate of their ends the standards 6 are provided with projections 18, which are adapted to be inserted in the sleeves 3, one of which projections is provided with a groove 19, adapted to be engaged by the spring 5, carried by one of the sleeves 3, so that the treadle is held steady in its position at one end of the table. When the projections 18 are withdrawn from the sleeves 3, the-standards 6 may be folded downward against the treadle 14 on the pivot 13 by releasing the bent ends 17 of the spring 17 from engagement with the adjacent standard 6. The treadle may then be disposed out of the way.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 4 1. In combination with a table, a pair of sleeves secured to the table, a treadle provided with members adapted to be inserted within the sleeves, and means for locking said members within the sleeves.

2. In combination with a table, a pair of sleeves having lugs secured to the table, a spring on one of the lugs, and atreadle having projections disposed in the sleeves and provided with a groove in one of the projections adapted to be engaged by the spring.

3. In combination with a table, a treadleframe, means for removably securing the frame to the table, said frame comprisingstandards, and a horizontal member pivoted to one of the standards, and means for looking the horizontal member against movement.

4. In combination with a table, a treadleframe, means for removably securing the frame to the treadle, said frame comprising standards, and a horizontal member pivoted to the standards and provided with a bent free end, and means for locking the horizontal member against movement.

Secured adjacent the ""to the horizontal member and adapted to engage one of the standards.

6. In combination with a table, a treadleframe, means for 'removably securing the treadle-frame to the table, said frame comprising standards, and a horizontal member pivoted to the standards, {a {spring secured to the horizontal member and adapted to engage one of the standards, atreadle carried by the horizontal member, a driving-wheel carried by the standards and a connection between the treadle and the driving-wheel.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

STANISLAS DENIS BACHAND.
